Manual override and PIR on lights 31C7ECC6-986B-4EA0-B413-37BBF4340A7F - EletriciansForums.net Manual override and PIR on lights CC65A797-2575-4BFE-942E-DDA49128B13D - EletriciansForums.net Hi what’s difference between 1 way and 2 Way Switch please on manual override of pir
1 Way, Switch up is PIR and Switch down is perm on
Can someone explain how would the 2 way would work and is the drawings correct the load cable for the lights is from PIR as easier than wiring from switch thanks
 
The second drawings doesn't look correct. The Switch Live for the first switch looks like its going to the supply. Switch 2 will act like switch 1 in the first pic.

Ignore above... Brain fart moment..

The first drawing is simply an override of the sensor. The live to the sensor is always there and will always work.

The second drawing has an isolator for the live so there is a way that the sensor will not work at all.

2 gang switch, not 2 way. That’s something different.
 
There's 3 ways to do it.

Switch on the permanent live. This means the light can be turned fully off. Turning on the switch supplies power to the sensor, which in turn turns on the light when it detects something.
Common when you are replacing an existing light with a sensor version.

Over ride switch. Power is always on to the sensor - meaning it will work when it detects something, and will never be able to be switched off.

Combination of both of these. So the light can be always OFF, always ON, or sensor controlled. This can be done by a 3 position switch, or a combination of 2 x 1 way switches as per your diagrams.

It is the specification of the customer or the job in hand, so there is no right or wrong way out of those 3 options.

Also, there are some sensors that operate an override if you flick the switch on-off-on within a second.
 
Thanks for your help I just wanted to know different ways of how to manual override a pir
So I’ve found 1 gang

Thanks that’s all I wanted, I will do some diagrams in a bit of these 3 methods so I can always have it and remember how it’s done
